grid

创建菜单         

<ul id="menu1" class="mini-menubar" style="width:100%;" 
    url="../data/listMenu.txt" idField="id" parentField="pid">
</ul>

url数据格式

[
    { id: "1", text: "文件(F)"},        
    '-',
    { id: "2", text: "新建", iconCls: "icon-new", pid: "1"},    
    { id: "3", text: "文件", pid: "2"},
    { id: "4", text: "文件夹", pid: "2"},        
    { id: "5", text: "打开", iconCls: "icon-folderopen", pid: "1"},
    { id: "6", text: "保存", pid: "1"},
    { id: "7", text: "关闭", pid: "1"},
        
    { id: "8", text: "编辑(E)"},
    { id: "9", text: "剪切", iconCls: "icon-cut", pid: "8"},
    { id: "10", text: "复制", pid: "8"},
    { id: "11", text: "粘贴", pid: "8"},
        
    { id: "12", text: "查看(V)"},
    { id: "13", text: "帮助(H)", iconCls: "icon-help"}
]

参考示例：ToolBar：工具栏
                   

创建工具栏      

<div class="mini-toolbar">
    <a class="mini-button" iconCls="icon-add">增加</a>
    <a class="mini-button" iconCls="icon-edit">修改</a>
    <a class="mini-button" iconCls="icon-remove">删除</a>
    <span class="separator"></span>
    <a class="mini-button" plain="true">增加</a>
    <a class="mini-button" plain="true">修改</a>
    <a class="mini-button" plain="true">删除</a>
    <span class="separator"></span>
    <input class="mini-textbox" />   
    <a class="mini-button" plain="true">查询</a>
</div>

            

复杂工具栏

<div id="toolbar1" class="mini-toolbar" style="padding:2px;">
    <table style="width:100%;">
        <tr>
        <td style="width:100%;">
            <a class="mini-menubutton" plain="true" menu="#popupMenu">文件</a>
            <a class="mini-button" iconCls="icon-addfolder" plain="true" enabled="false">增加</a>
            <a class="mini-button" iconCls="icon-edit" plain="true">修改</a>
            <a class="mini-button" iconCls="icon-remove" plain="true">删除</a>
            <span class="separator"></span>
            <a class="mini-button" iconCls="icon-reload" plain="true">刷新</a>
            <a class="mini-button" iconCls="icon-download" plain="true">下载</a>
        </td>
        <td style="white-space:nowrap;"><label style="font-family:Verdana;">Filter by: </label>
            <input class="mini-textbox" />
            </td>
        </tr>
    </table>
</div>

参考示例: TreeGrid:节点拖拽    
                

创建代码    

<div id="treegrid1" class="mini-treegrid" style="width:600px;height:280px;"     
    url="../data/tasks.txt" showTreeIcon="true" 
    treeColumn="taskname" idField="UID" parentField="ParentTaskUID" resultAsTree="false"
    allowDrag="true" allowDrop="true">
    <div property="columns">
        <div type="indexcolumn"></div>
        <div name="taskname" field="Name" width="200">任务名称</div>
        <div field="Duration" width="100">工期</div>
        <div field="Start" width="100" dateFormat="yyyy-MM-dd">开始日期</div>
        <div field="Finish" width="100" dateFormat="yyyy-MM-dd">完成日期</div>
    </div>
</div>                     

• allowDrag：允许拖拽节点               
• allowDrop：允许投放节点

监听处理"drawcell"事件         

使用"drawcell"事件，可以自定义单元格内容、样式、行样式等。

function onDrawCell(e){
    var node = e.node,
        column = e.column,
        field = e.field,
        value = e.value;

    //格式化日期
    if (field == "Finish") {
        if (mini.isDate(value)) e.cellHtml = mini.formatDate(value, "yyyy年MM月dd日");
    }
    //工期
    if (field == "Duration") {
        e.cellHtml = value + "天";
    }
    //进度
    if (field == "PercentComplete") {
        e.cellHtml = '<div class="progressbar">'
                        + '<div class="progressbar-percent" style="width:' + value + '%;"></div>'
                        + '<div class="progressbar-label">' + value + '%</div>'
                    +'</div>';
    }
};

创建代码

<div id="treegrid1" class="mini-treegrid" style="width:600px;height:250px;"     
    url="../data/TreeService.aspx?method=LoadNodes" showTreeIcon="true" textField="text" idField="id" 
    treeColumn="filename" onbeforeload="onBeforeTreeLoad">
    <div property="columns">
        <div name="filename" field="name" width="150">名称</div>
        <div field="type" width="100">类型</div>
        <div field="size" width="100" dateFormat="yyyy-MM-dd">大小</div>
        <div field="createdate" width="100" dateFormat="yyyy-MM-dd">创建日期</div>
    </div>
</div>

服务端返回数据

[{
    id: "form",
    text: "Form",
    ......
    isLeaf: false,                            //是否叶子节点：+和-号
    expanded: false                            //节点处于收缩状态
},
......
]

懒加载事件         

当用户点击"+"图标时，会自动加载下一级节点，此时会把当前节点id传递到后台，也可以拦截加载事件，增加额外属性：

function onBeforeTreeLoad(e) {
    var tree = e.sender;    //树控件
    var node = e.node;      //当前节点
    var params = e.params;  //参数对象

    //可以传递自定义的属性
    params.myField = "123"; //后台：request对象获取"myField"
}

服务端处理          

服务端通过request获取"id"属性后，加载此节点的下一级节点数组，并通过JSON返回。

String id = Request["id"];
if (String.IsNullOrEmpty(id)) id = "-1";

//获取下一级节点
String sql = "select * from plus_file where pid = '" + id + "' order by updatedate";
ArrayList folders = DBUtil.Select(sql);

//判断节点，是否有子节点。如果有，则处理isLeaf和expanded。
for (int i = 0, l = folders.Count; i < l; i++)
{
    Hashtable node = (Hashtable)folders[i];
    String nodeId = node["id"].ToString();

    String sql2 = "select * from plus_file where pid = '" + nodeId + "' order by updatedate";
    ArrayList nodes = DBUtil.Select(sql2);

    if (nodes.Count > 0)
    {
        node["isLeaf"] = false;
        node["expanded"] = false;
    }

}

//返回JSON
String json = PluSoft.Utils.JSON.Encode(folders);
Response.Write(json);

参考示：过滤树

filter节点过滤          

tree.filter(function (node) {
    var text = node.text ? node.text.toLowerCase() : "";
    if (text.indexOf(key) != -1) {
        return true;
    }
});

clearFilter取消过滤         

tree.clearFilter();

参考示例：树右键菜单

一：创建ContextMenu     

<ul id="treeMenu" class="mini-contextmenu"  onbeforeopen="onBeforeOpen">        
    <li iconCls="icon-move" onclick="onMoveNode">移动节点</li>
    <li class="separator"></li>
    <li>
        <span iconCls="icon-add">新增节点</span>
        <ul>
            <li onclick="onAddBefore">插入节点前</li>                
            <li onclick="onAddAfter">插入节点后</li>    
            <li onclick="onAddNode">插入子节点</li>                 
        </ul>
    </li>
    <li name="edit" iconCls="icon-edit" onclick="onEditNode">编辑节点</li>
    <li name="remove" iconCls="icon-remove" onclick="onRemoveNode">删除节点</li>        
</ul>

二：设置contextmenu   

<ul id="tree1" class="mini-tree" url="../data/tree.txt" style="width:200px;padding:5px;" 
    showTreeIcon="true" textField="text" idField="id" 
    contextMenu="#treeMenu">        
</ul>

三：监听beforeopen事件   

function onBeforeOpen(e) {
    var menu = e.sender;
    var tree = mini.get("tree1");

    var node = tree.getSelectedNode();
    if (!node) {
        e.cancel = true;
    }
    if (node && node.text == "Base") {
        e.cancel = true;
        //阻止浏览器默认右键菜单
        e.htmlEvent.preventDefault();
        return;
    }

    ////////////////////////////////
    var editItem = mini.getbyName("edit", menu);
    var removeItem = mini.getbyName("remove", menu);
    editItem.show();
    removeItem.enable();

    if (node.id == "forms") {
        editItem.hide();
    }
    if (node.id == "lists") {
        removeItem.disable();
    }
}

参考示例：自定义节点

创建代码         

<ul id="tree1" class="mini-tree" url="../data/tree.txt" style="width:200px;padding:5px;" 
    showTreeIcon="true" textField="text" idField="id" 
    ondrawnode="onDrawNode" showCheckBox="true">        
</ul>           

此时，我们监听了“drawnode”事件。

drawnode 事件         

function onDrawNode(e) {
    var tree = e.sender;
    var node = e.node;

    var hasChildren = tree.hasChildren(node);

    //所有子节点加上超链接
    if (hasChildren == false) {
        e.nodeHtml = '<a href="http://www.miniui.com/api/' + node.id + '.html" target="_blank">' + node.text + '</a>';
    }

    //父节点高亮显示；子节点斜线、蓝色、下划线显示
    if (hasChildren == true) {
        e.nodeStyle = 'font-weight:bold;';
    } else {
        e.nodeStyle = "font-style:italic;"; //nodeStyle
        e.nodeCls = "blueColor";            //nodeCls
    }

    //修改默认的父子节点图标
    if (hasChildren == true) {
        e.iconCls = "folder";
    } else {
        e.iconCls = "file";
    }

    //父节点的CheckBox全部隐藏
    if (hasChildren == true) {
        e.showCheckBox = false;
    }
}
